To all whom it may concern:

Be it known thatI, CH RLEs F. BURGESS,

a citizen of the United States, residing at. Ma dison', in the county of Dane, State of l Visconsin, have invented certain'new and useful Improvements in Battery Hand- Lamps; and I do hereby declare the owing to be a 'full, clear,"and'exact description ofthc invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to battery hand lamps of a type inwhich the battery is composed of a plurality of dry cells permanently connected together to form-a unitary, rigid-structure, which'is serviceable as the body or handleof the device, and to one end of which a lamp may be detachably connected. In hand lamps of the present inventicm, .the battery. or body portion may be discarded when the cells of the battery become exhausted and a new battery substituted. The initial cost of the complete equipn'ient is low, and as compared Withmany hand lamps now in use, there is a very considerable reduction in weight through I elimination of the heavy fiber or metal. casis inexpensive, .and is possessed of, many ing in which the batteries ofsuch devices a are housed.

The present invention provides asupport for the lamp which may be easily reversed in position upon the end of the battery of Special construction to pr'otectthe lamp from injury and to avoid the danger. of depleting the battery by accidental lighting" of the lamp. The construction of the'support also is convenient to manipulate, is easy to build,

obvious advantages, particularly when use inconjunction with the-s1')ecial battery here in described. Certain. preferred embodir ments of the-invention are illustrated'inthe accompanying drawing, in which- Figure 1 is a view principally in section of a battery composed of two dry cells and having a lamp support'attached to one end; Fig. 2 is a view in elevation of the lamp support of Fig.1;

Fig. 3 is a view principally in section showing the lamp suppert of Fig. 1 attached to the end of the battery ininvertedposition; and v Fig. 4 is a view of a modified form of a reversible support.

A and B. Each of the cells has a carbon electrode 10 tipped with a metallic cap 11 which forms one terminal thereof. The other electrode of each cell is in the form of a zinc cup 12'which also serves as a container for the electrolytic paste and the depolarizing material which constitute parts of each cell. The paste and material are retained within the cell by the pitch seal 13. The foregoing details may be varied in many ways. A wrapping of impregnated paper or other suitable material 1 preferably waterproofed, surrounds the zinc cup except for a small portion near the bottom thereof. This wrapping is turned over the top of the cell and extends inwardly toward theanetallie cap 11. Each of the cells of the battery, except the first one Afhas fitted tightly upon its uppeig ergd zi metallic cap 15 which extends inwardly: far enough to engage the upper face of terminal 11 to which it preferably issoldere d. When the cells are'placed'togcther as shown in Fig. 1, the

. zinc cup of one ccllfirests upon the cap 15 of. an adjacent cell, but in order to make a better electrical contact and to attach the.

material. The paper may be waterproofed'.

A conducting strip 18 is attached at its lower end to the exposed zinc cup of the second cell B. The conducting strip extends to the other end of the battery Where it is firmly held beneath and makes electrical connectiouwith a terminal cap 20 forced tightly overthe outer end of the cell A and provided with an aperture through which ac cess may be obtained to the. terminal 11. To protect the conducting strip 18, the entire battery, except for the cap 20, is covered with a wrapping 21 of paper, cloth or-other suitable material,-and if desired this wrappin may be waterproofed before or. after its application, as wlth China wood 011, or.

with paraflin or the like. Thebottom of the battery ma'y be coveredby, disk or cap ranged so that it may be reversed in order 22 also of insulating material; or the side wrapping may be folded in of the'lowermost cell. 7

With the construction above described,

over the bottom the two terminals of the battery are adjacent to one another in convenient relatlon for ready attachment to a current-consuming device; In -the present case the lamp support comprises a sleeve or casing 25 both ends of which are provided with slots 26 so that when the'casing is slipped over the end of the battery it may be firmly rctained 1n place byethe spring action of the material between the slots. Within the. casing. 25 is mounted an annular member 27 to the up- 'persend'of which' is attached a concave reflector 28 provided at its-inner end with a screw-threaded socket 29 adapted to receive may conveniently be moved,

' The device of the present invention is arthat the lamp may be placed on the end of the battery inthe position shown in Fig. 3 Where it is protected from injury. In order to attain this result, the lamp is arranged to slide" longitudinally within the sleeve 25 for a considerable distance in order to provide sufficient space at the opposite end of the sleeve for attachment to the end of the batterv. in inverted osition. This result is obtained by cutti g longitudinal slots 36 in the sideof thecasing' so that the support 27 maybe slipped through the casing from one end toward the other.

When the device is in the-position shown in Fig. 1, a partial rotation'of the lamp support by means of a twisting pressure on the buttons 35 will, by. virtue of the in-' l'clined portions of the slots, cause the inner terminal 32 of the lamp to'be brought into or-out of contact With the inner terminal oi.

the battery. Since the casing 25 is in electrical contact with the other terminal of the battery, circuit will he made. or broken through the lamp according as the pins 34 lick? the inner or outer ends of the inclined slo .Vhen the lamp is thus in position for lighting, the support therefor lies near the outer end of the sleeve 25 so that no portion of the latter tends to cut oli" the light from the lamp.

ed to carry the device-with thelamn in protected position, the casing is detached from the battery, the lamps sup port 1s slipped to the other end'ofthe CW3,- mg, and the sleeve 25 is attached to the end of the battery in reversed position, as shown batterv there is no danger'of short-chard" inlfiig. 3. I The bulb of the lamp is then out of con-tact with theend of the battery and its inner terminal.- does not extend beyond the exposed end of the sleeve 25 tint the lamp is properly protected and since here is no. metallic member which may COlra. in contact Wlth the inner terminal .11 01 "he ing the latter.

"In Fig. 4 is shown a modified embodin'rxwt of the invention in which the casing 25 of such a length that the lamp may be permanently fixed-at the center portions of this casing. The casing maybe applied tothe end of the battery in such a positionthat the inner terminal 32 of the lamp comes in oontact with the inner terminal of the battery or the casing maybe applied in reversed position, with sufiicient clearance between the end of the battery and the bulb of the lamp to prevent any danger of breakingthe latter.

.It will he understood that various changes in the, dotails of construction of the device principle of the invention.
